niDMM_RestoreLastExtCalConstants
ViStatus = niDMM_RestoreLastExtCalConstants(ViSession Instrument_Handle)
Purpose
Reverts the device to the calibration constants from the last complete external calibration. This function recovers the hardware if a fatal system error should occur during an external or self-calibration procedure.
For the NI 4070/4071/4072 only, after calling this function, you should call niDMM_SelfCal before taking measurements with the device to adjust the device for any temperature drifts since the last external calibration.
Note The NI 4050 and NI 4060 are not supported. |
